As of July 8th, 2015, teuthology (the Ceph integration test software) switched from using Chef to using Ansible. To keep it working, two files must be created. The /etc/ansible/hosts/group_vars/all.yml file with:
The modify_fstab is necessary for OpenStack provisioned instances but it won’t hurt if it’s always there (the only drawback being that mount options are not persisted in /etc/fstab, but they are set as they should). The /etc/ansible/hosts/mylab file must then be populated with
[testnodes] ovh224000.teuthology ovh224001.teuthology ...
where ovh224000.teuthology etc. are the fqdns of all machines that will be used as teuthology targets. The Ansible playbooks will expect to find all targets under the [testnodes] section. The output of a teuthology job should show that the Ansible playbook is being used with something like:
... teuthology.run_tasks:Running task ansible.cephlab... ... INFO:teuthology.task.ansible.out:PLAY [all] ***** ... TASK: [ansible-managed | Create the sudo group.] ****************************** ...
Prior to roles used by teuthology should not require a secrets repo the following had to be in /etc/ansible/hosts/group_vars/all.yml.
